Benefits of technology

The system simplifies the connection and control of LED lamps, reducing the number of transmission lines and eliminating stroboscopic lighting issues, while maintaining effective control over light parameters.

Problems solved by technology

In the color temperature adjustable control system, it is necessary to use a control line including two power lines, one for controlling the working state of the cool color LED lamps D1-Dn, which requires the overall cost of the lamp to be relatively high, and also it increases the difficulty of typography of the lighting lines, and is also not conducive to the control of the size of the lighting structure.

Abstract

An LED lamp control system comprises a power supply, a MOS transistor, a signal encoding module, a control signal input module, a signal change judging module, a MOS transistor control module, an LED lamp, a filter capacitor, and a signal decoding module, and a DC / DC converter. The signal encoding module is configured to convert the control signal output by the control signal input module into a PWM signal, and the output of the signal encoding module is connected to the gate of the MOS transistor and output a PWM signal to control the on and off of the MOS transistor, the signal decoding module is configured to convert a PWM signal loaded onto the power supply output which is connected to a MOS transistor to a dimming signal. The DC / DC converter controls the output parameters of the LED lamp according to the dimming signal. The invention makes the connection between the power supply and the LED lamp only use two wires to complete the connection between the lamp and the power supply, thereby helping to reduce the typographical difficulty of the lamp line and also facilitating the control of the structure size of the lamp.

Description

CROSS-REFERENCE TO A RELATED APPLICATION[0001]This application claims priority to a Chinese Patent Application No. CN 201711068251.3, filed on Nov. 3, 2017.FIELD OF THE TECHNOLOGY[0002]The present invention relates to lighting system, with particular emphasis on a LED lamp control system.BACKGROUND[0003]With the concept of “humanized lighting” deeply rooted in the hearts of the people, lighting design should create a good indoor lighting effect to meet the physiological and psychological requirements of people. The light-emitting parameters of the lamp are important factors in the lighting design, such as color temperature, brightness and other parameters, different color temperature or brightness gives different feelings, which can meet the needs of different people. Therefore, in some lamps, the above objectives are achieved by adjusting the illuminating parameters of the lamp. The existing adjustable control system of the lamp is composed of a power source, a controller and a lam...
